Ask Dr. Z

Pt had a positive finding for traumatic retro bleed found on CTA. Selective cath plmnts 2nd & 3rd lumbars, contralat. common, internal & ext iliacs w/embo of 3rd lumbar. dr also comments that in order to "locate" the lumbar artery's he also selected splenic, lt gatric, lt renal, and IMA. I feel those would be considered roadmapping or guiding shots so I did not code them. I've coded the following-37244,36245x2 for lumbars, 36246 for ext common iliac and 36248 for internal. No S&I's since CTA. Would this be correct or should I code what I think to be the guiding selective catheter plmnts also? Thanks in advance for your help!
